The finite element analysis and optimizations of shells of internal gear pumps based on ANSYS

In this paper, the shells of internal gear pumps of different materials were analyzed by ANSYS software to find the different applications between shells of dectile iron and shells of aluminum. Then, these two kinds of shells were optimized, which improved the overall performance of the gear pumps. Finally, the actual deformation of shells of gear pumps under different loads were measured. And the results were consistent with the results given by ANSYS. This method of analysis, optimization and experiment also has an important significance to develop the whole series of new gear pumps of different materials.
